What is the innovation of Q345NH weathering steel in the production process

Design and manufacture of Q345NH weathering steel

(1) choose better Q345NH weathering steel quality. The wear resistance and toughness of Q345NH weathering steel can be significantly improved by adding special alloying elements into ordinary high-speed tool steels.

(2) coating the thread surface of Q345NH weathering steel with titanium nitride coating can significantly improve the wear resistance, heat resistance and lubricity of Q345NH weathering steel.

(3) appropriately increase the front Angle of Q345NH weathering steel. However, it should be noted that if the front Angle of Q345NH weathering steel is too large, it is easy to cause the crack edge of Q345NH weathering steel and the polyedge of the thread that is attacked when rewinding the knife.
